1 Dorsal fins are found on the back of the fish. 2  There may be up to three of them. 3  The fish uses this fin for balance in the water and sudden movements. 4  Caudal fins are also known as tail fins.5  This is what we refer to as the fish's tail. 6  Anal fins are on the ventral (bottom) surface of the fish, behind the anus.

The oxidation number for phosphorus is +3: four covalent bonds with oxygen atoms yield +4 and the central charge yields -1. The oxidation numbers of oxygen and hydrogen are -2â¦ and +1 respectively. The oxidation number of the overall ion is -1.
Using the oxidation numbers of the the atoms that constitute the sulfate ion that has a formula of SO4, the oxidation state is determined by adding the oxidation number of sulfur and oxygen.Sulfur has an oxidation number of 6, or it loses 6 atoms when it forms a chemical compound.Oxygen atoms on the other hand accept 2 electrons each when they form a compound. The sulfate anion has a formula of SO4, this gives a net oxidation state of +6 + 4*(-2) = -2.osted on. (Answer #1). The oxidation number refers to the charge on the central atom of a compound when the ligands attached to it are removed and so are the atoms that associated with the ligand. For the sulfate anion it is the oxidation state that can be determined not the oxidation number.
